[0002] In the construction of water conservancy projects, gravel devices play a crucial role in crushing large stones into small-sized gravel that meets the engineering requirements. However, existing gravel devices still have some significant drawbacks in practical applications. Firstly, some devices lack effective protection measures during the crushing process, resulting in gravel splashing, which not only reduces work efficiency but also poses a safety hazard to surrounding operators. Secondly, the screening system after gravel crushing is not perfect enough to efficiently separate gravel that does not meet the particle size requirements, easily causing gravel accumulation and affecting the construction progress and quality. In addition, the structural design of some equipment is complex, with high maintenance costs and large energy consumption, which does not conform to the current development trend of energy conservation and environmental protection. Finally, existing gravel devices also generate a large amount of dust during operation, which has a greater impact on the local air quality. Therefore, there is an urgent need for a gravel device for water conservancy project construction that is reasonably designed, easy to operate, safe, efficient, energy-saving, and environmentally friendly to solve the above problems and improve the quality and efficiency of water conservancy project construction.
